A Metric for Quantitative Estimation of Production Process Resilience Based on the Skills and Knowledge of Production Plant Personnel in the Chemical Industry

摘要

The products and the capacity of production in the production process in the chemical industry depend on the design specification of the units. And many disruptions exist on the production process. Therefore, a company that aims to maximize the profit from the operation of a production process needs to restrain the influence of disruptive signals, and the capacity of the production process to restrain their negative effects is called the resilience. To maintain productivity, the company must improve the resilience. In this paper, the authors propose a metric for the quantitative estimation of resilience based on the skills and knowledge of production plant personnel on the production process in the chemical industry using the value of skills estimated quantitatively by the real measured value of skills of production plant personnel working at the production process. The value of skills is composed of the proficiency (level of skills and knowledge) and the labor efficiency (work hours devoted to skills), and it is possible 1) to estimate the averaged resilience of a work team by the potential capability of production plant personnel to compare the resilience of several production process, and 2) to know the change or trend of resilience in a single production process. It is possible to evaluate the metric of resilience commonly no matter what kind of process or number of the production plant personnel.
